6. Scope of use
Before the mechanical equipment starts to operate, it must be matched
with the appropriate parameter settings.Failure to adjust to a suitable
setting may result in loss of control or malfunction of the machine.
Before starting operation, please confirm whether the emergency switch
can be started at any time.
Please test the servo motor for normal operation without load, and then
connect the load to avoid unnecessary loss.
Do not turn the power on and off frequently, as this may cause
overheating inside the drive.
When the motor is running, it is forbidden to touch any rotating parts,
otherwise it will cause casualties.
Do not touch the driver and motor while the device is running, otherwise
it may cause electric shock or burns.
Do not touch the inside of the drive and its motor, as this may result in
electric shock.
Do not remove the drive panel when the power is turned on, otherwise it
may cause electric shock.
Do not touch the terminals until the power is off for 5 minutes,
otherwise residual high voltage may cause electric shock.

not use on devices that may directly endanger personal safety, such as
nuclear power equipment, aerospace equipment, life support and maintenance

Chapter 1 Product Inspection and Installation
1.1 Product inspection
This product has been fully functional tested before leaving the factory. To prevent the
product from being abnormal due to negligence during the product delivery process, please
check the following items after unpacking:
Check that the servo drive and servo motor models are the same as the ones ordered.
Check the appearance of the servo drive and servo motor for damage and scratches.Do
not wire the power when it is damaged during transportation.
Check if the servo drive and servo motor are loose.Is there a loose screw, if the screw is
not locked or comes off?
Check if the servo motor rotor shaft can rotate smoothly with the hand.Motors
with brakes cannot be rotated directly.If any of the above items are
malfunctioning or abnormal, please contact your dealer immediately.
1.2 Installation and wiring
Installation in electrical control cabinet
The heat of the electrical equipment inside the electrical control cabinet and the heat
dissipation conditions in the control cabinet, the temperature around the servo drive will
continue to rise, so considering the cooling of the drive and the configuration inside the
control cabinet, the long-term safe working temperature is below 40 °c.
There is a heating device near the servo drive
Servo drives operating at high temperatures can significantly shorten their life and cause
malfunctions.Therefore, the servo drive should be kept below 40 °c under conditions of
thermal convection and heat radiation.
Vibration equipment near the servo drive
Various anti-vibration measures are adopted to ensure that the servo drive is not affected by
vibration, and the vibration is guaranteed to be below 0.5G (4.9m/S2).
Servo drive for use in harsh environments
When the servo drive is used in a harsh environment, it is exposed to corrosive gases,
moisture, metal dust, water, and processing liquids, which may cause the drive to
malfunction.Therefore, when installing, you must ensure the working environment of the
drive.
Interference equipment near the servo drive
When there is interference device near the servo driver, it will have a large interference
effect on the power cable and control line of the servo driver, causing the driver to

malfunction.Noise filters and other various anti-interference measures can be added to
ensure the normal operation of the drive.Note that after adding a noise filter, the leakage
current will increase. To avoid this problem, an isolation transformer can be used.Pay
special attention to the control signal line of the driver is very susceptible to interference,
and there must be reasonable wiring and shielding measures.
1.3 installation method
Installation direction
The normal installation direction of the servo drive is the vertical upright direction.
Fixed installation
When installing, tighten the four m5 setscrews on the rear of the servo drive.
Installation interval
Please refer to Figure 1.1 for the installation distance between the servo drives and other
devices. Note that the minimum size is indicated on the drawing. In order to ensure the
performance and life of the drive, please leave as much installation interval as possible.
Heat dissipation
The servo drive adopts the natural cooling method, and a cooling fan must be installed in
the electric control cabinet to ensure that the vertical direction of the wind dissipates heat
to the heat sink of the servo drive.
Installation Precautions
Prevent dust or iron filings from entering the servo drive when installing the electrical control
cabinet.

1.4 Servo motor installation
1.4.1 Installation environmental conditions
Working environment temperature: 0~40°C; working environment humidity: 80% or less (no
condensation).
Storage environment temperature: -40~50 °C; storage environment humidity: 80% or less (no
condensation).
Vibration: 0.5g or less.
A well ventilated place with less moisture and dust.
Non-corrosive, igniting gas, oil and gas, cutting fluid, cutting powder, iron powder and other
environments.
A place where there is no water vapor and direct sunlight.
1.4.2 installation method
Horizontal installation: To prevent water, oil and other liquid from flowing into the motor
from the motor outlet, place the cable outlet below.
Vertical installation: If the motor shaft is mounted upwards and the gear unit is attached,
care must be taken to prevent oil in the gear unit from penetrating into the motor through
the motor shaft.
The amount of protrusion of the motor shaft needs to be sufficient. If the amount of protrusion
is insufficient, it will easily cause vibration when the motor moves.
When installing and removing the motor, do not hit the motor with a hammer, otherwise the
motor shaft and encoder may be damaged.
1.5 Motor rotation direction definition
The motor rotation direction defined in this manual is defined as: facing the motor shaft
extension, the rotation axis rotates counterclockwise (ccw) for forward rotation, and the rotation
shaft rotates clockwise (cw) for reverse rotation.
Figure 1.2 Motor rotation direction definition

Chapter 2 Wiring
2.1 Wiring specification
Wire diameter: R, S, T, PE, U, V, W terminal wire diameter ≥ 1.5mm2(AWG14-16), r, t
terminal wire diameter ≥
0.75mm2(AWG18)。
The terminals are pre-insulated cold-pressed terminals and must be firmly connected.
It is recommended to use a three-phase isolation transformer for power supply
2.2 Wiring method
For the input/output signal line and the encoder signal line, use the recommended cable or
similar shielded cable. The wiring length is: Input/output signal line is 3m or less, and
encoder signal line is 20m or less.When wiring, connect at the shortest distance. The
shorter the better, the main circuit wiring and signal line should be separated.
The grounding wire should be thick and made a little grounded. The grounding terminal of the
servo motor and the grounding terminal of the servo driver pe
Be sure to connect.
To prevent malfunction caused by interference, it is recommended to install a noise filter and
note that:
1) The noise filter, servo driver and host controller are installed as close as possible.
2) Surge suppressors must be installed in coils such as relays, electromagnetic contactors, and
brakes.
3) Do not pass the main circuit and signal lines through the same pipe and do not tie them
together.
When using strong interference sources nearby (such as electric welders, electric spark
machines, etc.), using an isolation transformer on the input power supply can prevent
malfunctions caused by interference.
Install a non-fuse type circuit breaker (nfb) to cut off the external power supply when the drive
fails.
Connect the cable shield correctly.
2.3 Precautions
The terminals of the drivers u, v, and w must be in one-to-one correspondence with the
motor terminals u, v, and w. Note that the motor cannot be reversed by changing the
three-phase terminals, which is completely different from the asynchronous motor.
Since the servo motor flows through the high-frequency switching current, the leakage
current is relatively large, and the motor ground terminal must be connected to the servo
driver ground terminal pe and grounded well.

Since there is a large-capacity electrolytic capacitor inside the servo driver, even if the
power is turned off, there is still a high voltage in the internal circuit.After the power is
turned off, wait at least 5 minutes before touching the drive and motor.
After turning on the power, the operator should keep a certain distance from the drive and
motor.
If it is not used for a long time, please cut off the power.
